A device for treating uranium tailings with microorganism is provided and includes a treatment container, a spray water distribution assembly, a microbial incubator and a first pump. The water is transported from the microbial incubator to the spray water distribution assembly through the first pump, allowing the microorganisms to enter the interior of the uranium tailings in the treatment container. After treatment is completed, the water is collected by the water collection cylinder and sent back to the microbial incubator for recovery, so as to reduce the waste of microorganisms. The even distribution of horizontal spray pipes can evenly spray water containing microorganisms on the uranium tailings in the treatment container, which makes the distribution of microorganisms in the uranium tailings more uniform and can prevent inadequate treatment and improve the treatment efficiency of microorganisms on uranium tailings.

Method of immobilizing nuclear waste comprising: a mixing step during which nuclear waste is mixed with a mineral composition and water, a drying step during which the mixture obtained in the mixing step is dried so as to form an immobilizing matrix,
characterized in that the mineral composition is obtained by a manufacturing process that comprises the steps consisting of: preparation of a base comprising a predetermined quantity of a mineral material synthesized by at least one part of a living structure selected from the vegetable kingdom, animal kingdom and/or microorganisms; and treatment of said base so as to convert it into an inactivated material with a predefined texture.
